CHURN.

Specification of Letters Patent.

Patented May Application filed June 23, 1909.

being readily disassemb ed for cleansingl purposes.

Another object of the invention is to pro vide a dasher which will servethe function of a gatherer by which a large amount of the butter may beremoved from the churn at the completion of the churning operation andthe skimmed milk simultaneously drained therefrom.

Still another object of the invention is to provide a thermometer bywhich the temperature of the body of the cream may be determined at anytime, so that the cream may be tempered whenever necessary.

YVith these and other objects in view, the invention consists of thefeatures of construction, combination and arrangement of partshereinafter fully described and claimed, reference being had to theaccompanying drawing, in which Figure 1 is a vertical section through achurn embodying my invention. Fig. 2 is a top plan view of the lowerdasher head or disk. Fig. 3 is a perspective view of one of the dasherblades. Fig. 4 is a vertical section through the hollow shaft anddasher.

Referring to the drawing, 1 designates the churn casing, which may be ofany preferred form and which is adapted to be closed at the top by aremovable lid or cover 2. This cover is provided with depending bearings3 having threaded orifices for the reception of clamping screws 4, saidscrews being provided with pointed ends to engage the churn body,whereby the lid may be firmly fastened in position.

Risin from the lid is a post or standard 5 provided upon one side withbearings 6 for a vertical dasher shaft 7 which extends downwardlythrough an opening in the lid 2 a suitable distance into the body orcasing 1. On said shaft is a beveled gear 8 meshing with a correspondingdrive gear 9 on a horizontal drive shaft 10 journaled in the' standardand provided with an operating crank handle 11, by which rotary motionmay be imparted to the shaft.

The lower end of the shaft carries a dasher consisting of upper andlower heads or disks 12 and 13 and an intermediate series of blades 14.The head or disk 12 is provided with a collar 15 by which it is fittedupon the shaft 7 immediately above the lower end thereof, said collarcarrying a set screw 16 for clamping said head to the shaft.

The lower dasher head or disk 13 is provided with a concaved or dishedupper face 17 having a central seat recess 18, and in said head areformed annular rows or series of drainage openings 19. Each blade 14 isapproximately of oblong rectangular form and provided with creampassages or apertures 20, the opposite inner and outer end edges of theblades being, however, curved, as indicated at 21 to diminish itsresistance to its passage through the cream, said end edges being formedwith tongues or offsets 22 which fit within sockets or recesses 23formed within theopposing faces of the heads 12 and 13. Set screws orother equivalent 24 are provided upon the heads to secure the tonguesthereto, by which the parts of the dasher are detachably united, so thatthey may be disassembled after each churning operation to permit them tobe thoroughly cleansed.

WVhen the churning operation is completed, it will be understood thatthe lid, dasher and its drive gearing are detached to permit of theremoval of the butter and skimmed milk. The construction of the dasherhead 13 facilitates the removal of the butter, as its concaved face 17serves as a gatherer into which a large amount of the butter will settleby gravity when the motion of the dasher is arrested, which butter willbe withdrawn with the dasher when the latter is extracted. The openings19 in the dasher head 13 permit the skimmed milk to drain from thebutter contained thereon as soon as the dasher is elevated above thebody of skimmed milk as will be readily understood. If desired, the lid2 may be pro" vided with a funnel or other receptacle 25 for theintroduction of hot or cold water into the churn casing to temper thecream during the process of churning as circumstances may require.

In order that the temperature of the body of cream may be determined atany time, so that the cream may be accurately tempered, the shaft 7 ismade hollow for the passage of a thermometer 26 or other temperatureindicator, which is adapted to rest at its lower end in the seat recess18 of the head 13, by which it will be sustained and exposed at a pointwhere itwill be influenced by the temperature of the body of cream toaccurately indicate the same. The said thermometer is attached to thelower end of a rod or other extracting device 27 extending upwardly tothe exterior through the ho]- low shaft and provided at its outer endwith a finger piece 28 and a stop 29, the latter being adapted to engagethe upper end of said shaft to limit the inward movement of the rod. Atintervals during the operation of churning, the operator may, bywithdrawing the thermometer in an obvious manner, readily andconveniently determine the temperature of the cream, so that the lattermay be tempered to facilitate the production of butter.

From the foregoing description, the construction and mode of operationof my improved churn will be readily understood and its conveniencesappreciated. Parts of the invention may be applied to churns of ordinary construction, so that the invention is not limited to the exactdetails shown, but may be varied within the scope of the appendedclaims.

I claim 1. A churn comprising a casing, a dasher operating therein, ahollow shaft connected with the dasher, a thermometer, and means forinserting and withdrawing the thermometer through the hollow shaft.

2. A churn comprising a casing, a hollow shaft extending therein,.adasher carried by said shaft, a thermometer carried by the dasher, andmeans for extracting said thermometer through said shaft for inspection.

3. A churn comprising a casing, a hollow shaft operating therein, adasher carried by said shaft and provided with a seat recess, athermometer resting within said seat recess, and an extracting deviceconnected with the thermometer for withdrawing the same through saidhollow shaft.

l. A churn comprising a casing, a shaft operating therein, a dashercarried by the shaft, a thermometer normally supported by the shaft anddasher, and an extracting rod extending through the shaft and connectedwith the thermometer, whereby the latter may be withdrawn from thecasing.

5. A churn comprising a casing, a hollow shaft journaled in andextending within and without. the casing, a dasher arranged within thecasing and mounted upon the lower end of the shaft, gearing connectedwith the upper end of the shaft for imparting rotary motion thereto, athermometer inclosed by the blades of the dasher and adapted to besupported by aportion of said dasher, a rod extending through the hollowshaft and connected with said thermometer, and a handle upon the upperend of the rod adapted to rest upon and close the upper end of theshaft, said rod and handle providing a means by which the thermometermay be inserted into the casing and withdrawn therefrom through saidhollow shaft.

In testimony whereof I affix my signature in presence of two witnesses.
